LinkedGeoData is an effort to add a spatial dimension to the Web of Data / Semantic Web. LinkedGeoData uses the information collected by the OpenStreetMap project and makes it available as an RDF knowledge base according to the Linked Data principles. It interlinks this data with other knowledge bases in the Linking Open Data initiative.

AKSW at TU Dresden PLTOn June 8, I (Jens) visited the process control engineering research group (PLT) of Leon Urbas at the Dresden University of Technology. We first met on the Leipziger Semantic Web Day where Leon Urbas presented interactive Linked Data applications and decided to have a longer meeting later on. I first gave a talk on the [...]

LinkedGeoData Release 2The AKSW research group is happy to announce a new release of LinkedGeoData! The aim of the LinkedGeoData (LGD) project is to make the OpenStreetMap (OSM) datasets easily available as RDF. As such the main target audience is the Semantic Web community, however it may turn out to be useful to a much larger audience. [...]

The Linked Geo Data Knowledge Base

In order to employ the Web as a medium for data and information integration, comprehensive datasets and vocabularies are required as they enable the disambiguation and alignment of other data and information. Many real-life information integration and aggregation tasks are impossible without comprehensive background knowledge related to spatial features of the ways, structures and landscapes surrounding us.

LinkedGeoData uses the comprehensive OpenStreetMap spatial data collection to create a large spatial knowledge base. It consists of more than 1 billion nodes and 100 million ways and the resulting RDF data comprises approximately 20 billion triples. The data is available according to the Linked Data principles and interlinked with DBpedia and Geo Names.

Wiki Contents

This Wiki provides information about the LinkedGeoData community project:

Datasets gives an overview about the LinkedGeoData knowledge base and allows to download the whole dataset.

Online Access describes how the data set can be accessed via Linked Data.

GADM used to state the following license, which seems to have been removed (overall the project seems dead): This dataset is freely available for academic and other non-commercial use. Redistribution, or commercial use, is not allowed without prior permission.

Updates

Completed upgrade to Postgres 9.3 and loaded a fresh LGD database. Please create issues in the git should you experience any problems. New downloads are in the works.

New datasets for download available here! Data in the SPARQL endpoint will be updated later.

Servers are back online after being down for the week because of moving them to a new location. Also, updated licence statements to ODbL, because we are required to do so – at least according to the OSM wiki
